Eastern Quakes can Trigger Big Shakes

In the first week of November 2011,people in central Oklahoma experienced more than two dozen
earthquakes.The largest,a magnitude 5.6 quake,shook thousands of fans in a college football itadium,
caused cracks in a few buildings and rattled the nerves of many people who had never felt a quake before.
Oklahoma is not an area of the country famous for its quakes.If you watch the news on TV,you will see
reports about all sorts of natural disasters一hurricanes,tornadoes,flooding and wildfires,to name a few.But
the most dangerous type of natural disaster,and also the most unpredictable,is the earthquake.
Researchers at the U.S.Geological Survey estimate that several million earthquakes rattle the globe each
year. That mnay sound scary,but people don'I feel many of the tremors because they happen in remote and
unpopulated regions.Many quakes happen under the ocean,and othlers have a very small magnitude,or
shaking intensity..
A magnitude 5.8 earthquake that struck central Virginia the afternoon of August 23,2011,was felt
from central Georgia to southeastern Canada.In iilany urbanl areas,including Washington,D.C.,dnd New
York City(Wall Street shown),people crowded the streets while engineer inspected buildings.Credit:
Wikimnedia/Alex Tahak.
Scientists know about small,remote quakes only because of very sensitive electronic devices called seis-
mometers.These devices detect and measure the size of ground vibrations produced by earthquakes.
Altogether,USGS researchers use seismornetero to identify and locate about 20,000 earthquaks
each year.
Although earthquakes can happen anywhere in the world,really big quakeg occur only in。erttiin areas.
The largest ones register a magnitude S or higher and happen, on average,only once each year. Such big
ones typically occur along the edges of Earth’s tectonic plates.
Tectonic plates are huge pieces of Earth’s crust,sornetinies many kilometers thick.These plates cover
our planet's
surface ike a jigsaw puzzle.Often,jagged edges of these plates temporarily lock together. When
riates jostle and serape past each other earthquakes occur. On。、crage,tectonic plates move very slowly一
about the same speed as sour fingernails grow.
But sometimes earthquakes rumble through portions of the landscape far from a plate'S edges.Although
less cxpcctcd,these"mid-plate"tremors can do substontaI damage,Some of the biggest known examples
rattled the eastern haif of the United States two centuries ago.Today,scientists are still puzzling over why the
quakes occurred and when similar ones nught occur.

Big earthquakes of a magnitude 8 or higher seldom happen far from the edges of tectonic plates.

2.共用题干 A Great Quake Coming?Everyone who lives in San Francisco knows that earthquakes are common in the Bay Area一and they can be devastating. In 1906,for example,a major quake destroyed about 28,000 buildings and killed hundreds,perhaps thousands of people.Residents now wonder when the next"Big One"will strike.It's bound to happen someday. At least seven active fault(断层)lines run through the San Francisco area. Faults are places where pieces of Earth ' s crust(地壳)slide past each other. When these pieces slip , the ground shakes.To prepare for that day,scientists are using new techniques to reanalyze the 1906 earthquake and pre-dict how bad the damage might be when the next one happens.One new finding about the 1906 earthquake is that the San Andreas fault split apart faster than scientists had assumed at the time. During small earthquakes,faults rupture(断裂)at about 2.7 kilometers per second. During bigger quakes,however,ruptures can happen at rates faster than 3.5 kilometers per second.At such high speeds,massive amounts of pressure build up,generating underground waves that can cause more damage than the quake itself. Lucky for San Francisco , these pressure pulses(脉冲)traveled away from the city during the 1906 event.As bad as the damage was,it could have been far worse.Looking ahead,scientists are trying to predict when the next major quake will occur. Records show that earthquakes were common before 1906.Since then,the area has been relatively quiet.Patterns in the data, however,suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62 percent.New buildings in San Francisco are quite safe in case of future quakes.Still,more than 84 percent of thecity's buildings are old and weak.Analyses suggest that another massive earthquake would cause extensive damage.People who live there today tend to feel safe because San Francisco has remained pretty quiet for a while.According to the new research,however,it's not a matter of"if" the Big One will hit.It's just a mat- ter of when.The highest speed of fault ruptures in the 1906 quake was more than 3.5 kilometers per second.A:RightB:WrongC:Not mentioned

    Study Helps Predict Big Mediterranean Quake

    1.Scientists have found evidence that an overlooked fault in the eastern Mediterranean is likely to produce an earthquake and tsunami every 800 years as powerful as the one that destroyed Alexandria in AD 365.
    2.Using radiocarbon dating techniques,simulations and computer models,the researchers recreated the ancient disaster in order to identify the responsible fault."We are saying there is probably a repeat time of 800 years for this kind of earthquake,"said Ms Beth Shaw,an earthquake scientist at the University of Cambridge,who led the study. Scientists study past earthquakes in order to deter-mine the future possibility of similar large shocks.
    3.Identifying the fault for the AD 365 earthquake and tsunami is important for the tens of millions of people in the region,Ms.Shaw said.The fault close to the southwest coast of Crete last produced a big enough quake to generate a tsunami about 1300,which means the next powerful one could come in the next 100 years,she added in a telephone interview.
    4.Ms.Shaw and her colleagues calculate the likely intervals by measuring the motion of either side of the fault to find how often such large earthquakes would have to occur to account for that level of motion,she said.Their computer model suggested an 8 magnitude quake on the fault would pro-duce a tsunami that floods the coastal regions of Alexandria and North Africa,the southern coast of Greece and Sicily all the way up the Adriati to Dubrovnik.This would be similar to the ancient quake in AD 365 that caused widespread destruction in much of Greece and unleashed a tsunami that flooded Alexandria and the Nile Delta likely killing tens of thousands of people,she said.

    Scientists predict that the next powerful earthquake in the eastern Mediterranean may take place some time before 2100.
    A:Right
    B:Wrong
    C:Not mentioned

    答案:A
    解析:
    本题给出的信息是正确的。根据题目中的提到的overlook和fault,使用关键词定位法,定位到文章第一段话:" Scientists have found evidence that an overlooked fault in the eastern Mediterranean is likely to produce an earthquake and tsunami every 800 years as powerful as the one that destroyed Alexandria in AD 365.”公元365年,东部地中海地区发生特大地震和海啸,摧毁了亚历山大市,科学家们已经找到了证据证明:那里存在的一直被人忽视的断层,每隔800年就有可能就引发一次强地震和海啸。这与本题所描述的“科学家已经仔细研究了这个此前一直被忽略的断层”相符,所以选A。
    本题给出的信息是错误的。选择题目中较独特的短语“AD 365”作为关键词进行信息定位,找到文章第三段第一句话:" Identifying the fault for the AD 365 earthquake and tsunami is important for the tens of millions of people in the region , Ms.Shaw said.”肖女士说:对于地中海地区上千万的居民来说,确定是断层引发了公元365年地震和海啸非常重要。这与本题所描述的“确定是断层引发了公元365年地震和海啸非常有趣”相悖,所以选B。
    文章没有谈到这方面的信息。本题题干为:“放射性碳年代测定技术可以用于确定地球的年龄。”全文没有提到radiocarbon dating techniques可用来确定地球的年龄。所以选C。
    本题给出的信息是正确的。选择题干的关键词“next powerful earthquake",定位到文章第三段第二句话:" The fault close to the southwest coast of Crete last produced a big enough quake to generate a tsunami about 1300,which means the next powerful one could come in the next 100 years , she added in a telephone interview.”她在一次电话访问中补充说:克里特岛西南海岸附近的断层最后一次引发足以引起海啸的大地震是在公元1300年左右,这就意味着下一次强地震将在未来的100年中出现。这与本题所描述的“科学家预测下一次强地震将在2100年以前出现”一致,所以选A。
    本题给出的信息是正确的。选择“Ms.Shaw',这个称呼使用专有名词定位法进行定位,找到第四段第一句:"Ms.Shaw and her colleagues calculate the likely intervals by measuring the motion of either side of the fault to gauge how often such large earthquakes would have to occur to account for that level of motion.”肖女士和她的同事测量了断层两侧的震动强度,并确定大规模地震多久发生一次才会引起这样的震动强度,从而推算出地震产生的大致间隔时间。这与本题所描述的“肖女士让她的同事帮她做地震的预测工作”一致,所以选A。
    本题给出的信息是错误的。题干的意思是:“肖女士和她的研究组测量了断层两侧的震动强度,确定了公元365年地震的震级。”原文中与之相关的信息出现在第四段第一句中:"Ms.Shaw and her colleagues calculate the likely intervals by measuring the motion of either side of the fault to find how often such large earthquakes would have to occur to account for that level of motion.”肖女士和她的同事测量了断层两侧的震动强度,并确定大规模地震多久发生一次才会引起这样的震动强度,从而推算出地震产生的大致间隔时间。由于所表述的行为目的不同,这句恰恰证明了题干上的说法是错误的。所以选B。
    文章没有谈到这方面的信息。题干的意思是:“由肖女士研发的地震预警装置现在在全球广泛使用。”文章中没有一句提到肖女士发明过地震预测装置,更没有谈及这种装置在全世界得到广泛应用这一点,所以选C。

    Eastern Quakes Can Trigger Big Shakes
    In the first week of November 2011,people in central Oklahoma experienced more than two dozen earthquakes. The largest,a magnitude 5 .6 quake,shook thousands of fans in a college football stadium,caused cracks in a few buildings and rattled the nerves of many people who had never felt a quake before. Oklahoma is not an area of the country famous for its quakes. If you watch the news on TV,you see reports about all sorts of natural disasters一 hurricanes,tornadoes,flooding and wildfires,to name a few. But the most dangerous type of natural disaster,and also the most unpredictable,is the earthquake.
    Researchers at the U. S. Geological Survey estimate that several million earthquakes rattie the globe each year. That may sound scary,but people don't feel many of the tremors because they happen in remote and unpopulated regions.Many quakes happen under the ocean, and others have a very small magnitude,or shaking intensity.
    A magnitude 5.8 earthquake that struck central Virginia the afternoon of August 23, 2011,was felt from central Georgia to southeastern Canada. In many urban areas,including Washington,D.C.,and New York City(Wall Street shown),people crowded the streets while engineers inspected buildings.
    Scientists know about small,remote quakes only because of very sensitive electronic devices called seismometers.These devices detect and measure the size of ground vibrations
    produced by earthquakes.Altogether,USGS researchers use seismometers to identify and locate about 20,000 earthquakes each year.
    Although earthquakes can happen anywhere in the world,really big quakes occur only in certain areas. The largest ones register a magnitude 8 or higher and happen,on average,only once each year. Such big ones typically occur along the edges of Earth's tectonic plates.
    Tectonic plates are huge pieces of Earth's crust,sometimes many kilometers thick. These plates cover our planet's surface like a jigsaw puzzle. Often,jagged edges of these plates temporarily lock together. When plates jostle and scrape past each other,earthquakes occur. On average,tectonic plates move very slowly一about the same speed as your fingernails grow.
    But sometimes earthquakes rumble through portions of the landscape far from a plate's edges. Although less expected,these”mid-plate” tremors can do substantial damage. Some of the biggest known examples rattled the eastern half of the United States two centuries ago. Today,scientists are still puzzling over why the quakes occurred and when similar ones might occur.

    Seismometers can identify and locate most of the earthquakes in China.
    A: Right
    B: Wrong
    C: Not mentioned

    答案:C
    解析:
    题干意为“俄克拉荷马是一个经常遇到自然灾害的地区。”关键词为often,经 常。根据文中第一段第三、四句“Oklahoma is not an area of the country famous for its quakes.If you watch the news on TV,you see reports about all sorts of natural disasters一 hurricanes, tornadoes, flooding and wildfires, to name a few.”可知俄克拉荷马并不因地震 而闻名,其他类型的灾难也很少在电视上看到,由此可判断俄克拉荷马并不受灾难的眷顾。故此题说法为“错误”的。

    Eastern Quakes Can Trigger Big Shakes
    In the first week of November 2011,people in central Oklahoma experienced more than two dozen earthquakes. The largest,a magnitude 5 .6 quake,shook thousands of fans in a college football stadium,caused cracks in a few buildings and rattled the nerves of many people who had never felt a quake before. Oklahoma is not an area of the country famous for its quakes. If you watch the news on TV,you see reports about all sorts of natural disasters一 hurricanes,tornadoes,flooding and wildfires,to name a few. But the most dangerous type of natural disaster,and also the most unpredictable,is the earthquake.
    Researchers at the U. S. Geological Survey estimate that several million earthquakes rattie the globe each year. That may sound scary,but people don't feel many of the tremors because they happen in remote and unpopulated regions.Many quakes happen under the ocean, and others have a very small magnitude,or shaking intensity.
    A magnitude 5.8 earthquake that struck central Virginia the afternoon of August 23, 2011,was felt from central Georgia to southeastern Canada. In many urban areas,including Washington,D.C.,and New York City(Wall Street shown),people crowded the streets while engineers inspected buildings.
    Scientists know about small,remote quakes only because of very sensitive electronic devices called seismometers.These devices detect and measure the size of ground vibrations
    produced by earthquakes.Altogether,USGS researchers use seismometers to identify and locate about 20,000 earthquakes each year.
    Although earthquakes can happen anywhere in the world,really big quakes occur only in certain areas. The largest ones register a magnitude 8 or higher and happen,on average,only once each year. Such big ones typically occur along the edges of Earth's tectonic plates.
    Tectonic plates are huge pieces of Earth's crust,sometimes many kilometers thick. These plates cover our planet's surface like a jigsaw puzzle. Often,jagged edges of these plates temporarily lock together. When plates jostle and scrape past each other,earthquakes occur. On average,tectonic plates move very slowly一about the same speed as your fingernails grow.
    But sometimes earthquakes rumble through portions of the landscape far from a plate's edges. Although less expected,these”mid-plate” tremors can do substantial damage. Some of the biggest known examples rattled the eastern half of the United States two centuries ago. Today,scientists are still puzzling over why the quakes occurred and when similar ones might occur.

    A Great Quake Coming?

    Everyone who lives in San Francisco knows that earthquakes are common in the Bay Area一and they
    can be devastating. In 1906,for example,a major quake destroyed about 28,000 buildings and killed
    hundreds,perhaps thousands of people.Residents now wonder when the next"Big One"will strike.It's
    bound to happen someday. At least seven active fault(断层)lines run through the San Francisco area. Faults
    are places where pieces of Earth'S crust(地壳)slide past each other.When these pieces slip,the ground
    shakes.
    To prepare for that day,scientists are using new techniques to reanalyze the 1906 earthquake and pre-
    diet how bad the damage might be when the next one happens.
    One new finding about the 1906 earthquake is that the San Andreas fault split apart faster than scientists
    had assumed at the time. During small earthquakes,faults rupture(断裂)at about 2.7 kilometers per second.
    During bigger quakes,however.ruptures can happen at rates faster than 3.5 kilometers per second.
    At such high speeds,massive amounts of pressure build up,generating underground waves that can
    cause more damage than the quake itself. Lucky for San Francisco , these pressure pulses(脉冲)traveled
    away from the city during the 1906 event.As bad as the damage was,it could have been far worse.
    Looking ahead,scientists are trying to predict when the next major quake will occur. Records show that
    earthquakes were common before 1906.Since then,the area has been relatively quiet.Patterns in the data,
    however,suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62
    percent.
    New buildings in San Francisco are quite safe in case of future quakes.Still,more than S4 percent of the
    city’s buildings are old and weak.Analyses suggest that another massive earthquake would cause extensive
    damage.
    People who live there today tend to feel safe because San Francisco has remained pretty quiet for a
    while.According to the new research,however,it's not a matter of"if" the Rig One will hit.It',just a mat-
    ter of when.

    San Francisco is fully prepared br another big earthquake.

    第五段的第二句话提到1906年前地震频繁。
    倒数第二段提到:城里超过84%的建筑是旧的、不坚固的。所以旧金山并没有为地震做好准备。

    Moderate Earthquake Strikes England
    A moderate earthquake struck parts of southeast England on 28 April 2007,toppling chim- neys from houses and rousing residents from their beds .Several thousand people were left without power in Kent County. One woman suffered minor head and neck injuries.
    “It felt as if the whole house was being slid across like a fun-fair ride,”said the woman.
    The British Geological Survey said the 4 .3-magnitude quake struck at 8:19 a.m. and was centered under the English Channel,about 8 .5 miles south of Dover and near the entrance to the Channel Tunnel.
    Witnesses said cracks appeared in walls and chimneys collapsed across the county .Residents said the tremor had lasted for about 10 to 15 seconds.
    “I was lying in bed and it felt as if someone had just got up from bed next to me.”said Hen-drick van Eck,27,of Canterbury about 60 miles southeast of London.“I then heard the sound of cracking,and it was getting heavier and heavier. It felt as if someone was at the end of my bed hopping up and down.”
    There are thousands of moderate quakes on this scale around the world each year,but they are rare in Britain. The April 28 quake was the strongest in Britain since 2002 when a 4.8-magni-tude quake struck the central England city of Birmingham.
    The country's strongest earthquake took place in the North Sea in 1931,measuring 6.1 on the Richter scale.British Geological Survey scientist Roger Musson said the quake took place on 28 April in an area that had seen several of the biggest earthquakes ever to strike Britain,including one in 1580 that caused damage in London and was felt in France.Musson predicted that it was only a matter of time before another earthquake struck this part of England.However,people should not be scared too much by this prediction,Musson said,as the modern earthquake warning system of Britain should be able to detect a forthcoming quake and announce it several hours be-fore it takes place .This would allow time for people to evacuate and reduce damage to the mini-mum.

    The following statements are true Except______.
    A: the quake caused a power failure in Kent Country
    B: the tremor lasted for 10~15 seconds
    C: people in Canterbury felt strong quake
    D: the quake was centered under the Channel Tunnel

    答案:D
    解析:
    根据最后一段第一句“The country’s strongest earthquake took place in the North Sea in 1931...”可知,英国的最大地震发生于1931年。故本题选A。


    由该句可以知道,地震时墙壁断裂。因此烟囱就会倒塌。collapse意为“倒塌”,与fall apart意义相近。故选A。


    通读全文可知,文章前六段都在讲2007年4月28日发生的这次地震,因此this scale指的就是这次地震的“4 .3-magnitude”。


    根据第三段的“....and was centered under the English Channel...”可知,D项错误。由第一段“Several thousand people were left without power in Kent County.”可知,A项正确;根据第四段第二句可知,震感持续了10-15秒,B项正确;从第五段的描述中可知,C 项正确。因此本题选D。


    根据最后一段的“Musson predicted that it was only a matter of time before another earthquake struck this part of England.”可知,C项正确。

    an area of the country famous for its quakes.If you watch the news on TV,you will see reports about all sorts
    of natural disasters.But the most dangerous type of natural disaster,and also the most unpredictable,is the
    earthquake.
    Researchers at the US Geological Survey(USGS)estimate that several million earthquakes occur globally
    each year. That may sound scary,but people don't feel many of them because they happen in remote and
    unpopulated regions.Many quakes happen under the ocean,and others have a very small magnitude.
    Scientists know about small,remote quakes only because of very sensitive electronic devices called seis-

    Although earthquakes can happen anywhere in the world,really big quakes occur only in certain areas.
    The largest ones register a magnitude 8 or higher and happen,on average,only once each year. Such big
    ones typically occur along the edges of Earth ' s tectonic plates(构造板块).
    Tectonic plates are huge pieces of Earth ' s crust(外壳),sometimes many kilometers thick. Often,
    edges of these plates temporarily lock together. When plates push and scrape(擦)past each other earthquakes

    Big earthquakes of a magnitude 8 or higher seldom happen far from the edges of tectonic plates.
    A:Right
    B:Wrong
    C:Not mentioned

    答案:A
    解析:
    由文章第一段第三句话“Oklahoma is not an area of the country famous for its quakes.”可知,俄克拉荷马州不是美国以地震多发而扬名的州,故应选B。
    由文章第一段最后一句话“But the most dangerous type of natural disaster, and also themost unpredictable, is the earthquake”可知,应选A。
    由文章第二段第二句中“people don' t feel many of them because they happen in remoteand unpopulated regions”可知,在发生的多次地震中,只有很少的会被人们感觉到,因为多数的地震都发生在遥远的无人区,故选B。
    文章第三段中仅仅提到了地震仪能够监测到地震导致的地面震颤的面积和科学家们用这种仪器所监测到的地震数目,故选C。
    由文章第四段最后两句的内容可知,8级或更高的大地震多发于地壳构造板块的边缘,故选A。
    由文章第五段第三句“When plates push and scrape past each other earthquakes occur.”以及常识可知,地壳板块只有在相互推挤和摩擦时地震才会发生,并不是任何一次的板块移动都会导致地震,故选B。
    文章最后一段中提到,两个世纪前几次最强的板块中部地震袭击了美国东半部地区,但文中只说这些是已知的地震中最强的几次,并未表明这几次地震中的某一次地震是历史上 最强的,故选B。第3部分:概括大意与完成句子

    A Great Quake Coming?

    Everyone who lives in San Francisco knows that earthquakes are common in the Bay Area一and they
    can be devastating. In 1906,for example,a major quake destroyed about 28,000 buildings and killed
    hundreds,perhaps thousands of people.Residents now wonder when the next"Big One"will strike.It's
    bound to happen someday. At least seven active fault(断层)lines run through the San Francisco area. Faults
    are places where pieces of Earth ' s crust(地壳)slide past each other. When these pieces slip , the ground
    shakes.
    To prepare for that day,scientists are using new techniques to reanalyze the 1906 earthquake and pre-
    dict how bad the damage might be when the next one happens.
    One new finding about the 1906 earthquake is that the San Andreas fault split apart faster than scientists
    had assumed at the time. During small earthquakes,faults rupture(断裂)at about 2.7 kilometers per second.
    During bigger quakes,however,ruptures can happen at rates faster than 3.5 kilometers per second.
    At such high speeds,massive amounts of pressure build up,generating underground waves that can
    cause more damage than the quake itself. Lucky for San Francisco , these pressure pulses(脉冲)traveled
    away from the city during the 1906 event.As bad as the damage was,it could have been far worse.
    Looking ahead,scientists are trying to predict when the next major quake will occur. Records show that
    earthquakes were common before 1906.Since then,the area has been relatively quiet.Patterns in the data,
    however,suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62
    percent.
    New buildings in San Francisco are quite safe in case of future quakes.Still,more than 84 percent of the
    city's buildings are old and weak.Analyses suggest that another massive earthquake would cause extensive
    damage.
    People who live there today tend to feel safe because San Francisco has remained pretty quiet for a
    while.According to the new research,however,it's not a matter of"if" the Big One will hit.It's just a mat-
    ter of when.

    San Francisco is fully prepared for another big earthquake.
    A:Right
    B:Wrong
    C:Not mentioned

    答案:B
    解析:
    第一段提到:至少有7条活跃的断层线穿过旧金山。所以,此处讲“旧金山地区坐落在 数条活跃的断层线上”是正确的。
    短文只提到1906年地震的破坏性大,并没说它是最严重的。
    从第三段最后一句话可知答案。
    第五段第二句提到:记录显示1906年前地震频发。
    倒数第二段提到:城里超过84%的建筑是旧的、不坚固的。所以旧金山并未为地震做 好准备。
    短文没有谈到这方面的信息。
    短文末尾提到:问题已不再是“是否”将会发生大地震,而是“什么时候”会发生。所以, 这一地震是无法避免的。第3部分:概括大意与完成句子

    Study Helps Predict Big Mediterranean Quake

    1.Scientists have found evidence that an overlooked fault in the eastern Mediterranean is likely to produce an earthquake and tsunami every 800 years as powerful as the one that destroyed Alexandria in AD 365.
    2.Using radiocarbon dating techniques,simulations and computer models,the researchers recreated the ancient disaster in order to identify the responsible fault."We are saying there is probably a repeat time of 800 years for this kind of earthquake,"said Ms Beth Shaw,an earthquake scientist at the University of Cambridge,who led the study. Scientists study past earthquakes in order to deter-mine the future possibility of similar large shocks.
    3.Identifying the fault for the AD 365 earthquake and tsunami is important for the tens of millions of people in the region,Ms.Shaw said.The fault close to the southwest coast of Crete last produced a big enough quake to generate a tsunami about 1300,which means the next powerful one could come in the next 100 years,she added in a telephone interview.
    4.Ms.Shaw and her colleagues calculate the likely intervals by measuring the motion of either side of the fault to find how often such large earthquakes would have to occur to account for that level of motion,she said.Their computer model suggested an 8 magnitude quake on the fault would pro-duce a tsunami that floods the coastal regions of Alexandria and North Africa,the southern coast of Greece and Sicily all the way up the Adriati to Dubrovnik.This would be similar to the ancient quake in AD 365 that caused widespread destruction in much of Greece and unleashed a tsunami that flooded Alexandria and the Nile Delta likely killing tens of thousands of people,she said.

    Ms.Shaw measured the movement of either side of the fault to identify the magnitude of the earthquake taking place in AD 365.
    A:Right
    B:Wrong
    C:Not mentioned

    答案:B
    解析:
    本题给出的信息是正确的。根据题目中的提到的overlook和fault,使用关键词定位法,定位到文章第一段话:" Scientists have found evidence that an overlooked fault in the eastern Mediterranean is likely to produce an earthquake and tsunami every 800 years as powerful as the one that destroyed Alexandria in AD 365.”公元365年,东部地中海地区发生特大地震和海啸,摧毁了亚历山大市,科学家们已经找到了证据证明:那里存在的一直被人忽视的断层,每隔800年就有可能就引发一次强地震和海啸。这与本题所描述的“科学家已经仔细研究了这个此前一直被忽略的断层”相符,所以选A。
    本题给出的信息是错误的。选择题目中较独特的短语“AD 365”作为关键词进行信息定位,找到文章第三段第一句话:" Identifying the fault for the AD 365 earthquake and tsunami is important for the tens of millions of people in the region , Ms.Shaw said.”肖女士说:对于地中海地区上千万的居民来说,确定是断层引发了公元365年地震和海啸非常重要。这与本题所描述的“确定是断层引发了公元365年地震和海啸非常有趣”相悖,所以选B。
    文章没有谈到这方面的信息。本题题干为:“放射性碳年代测定技术可以用于确定地球的年龄。”全文没有提到radiocarbon dating techniques可用来确定地球的年龄。所以选C。
    本题给出的信息是正确的。选择题干的关键词“next powerful earthquake",定位到文章第三段第二句话:" The fault close to the southwest coast of Crete last produced a big enough quake to generate a tsunami about 1300,which means the next powerful one could come in the next 100 years , she added in a telephone interview.”她在一次电话访问中补充说:克里特岛西南海岸附近的断层最后一次引发足以引起海啸的大地震是在公元1300年左右,这就意味着下一次强地震将在未来的100年中出现。这与本题所描述的“科学家预测下一次强地震将在2100年以前出现”一致,所以选A。
    本题给出的信息是正确的。选择“Ms.Shaw',这个称呼使用专有名词定位法进行定位,找到第四段第一句:"Ms.Shaw and her colleagues calculate the likely intervals by measuring the motion of either side of the fault to gauge how often such large earthquakes would have to occur to account for that level of motion.”肖女士和她的同事测量了断层两侧的震动强度,并确定大规模地震多久发生一次才会引起这样的震动强度,从而推算出地震产生的大致间隔时间。这与本题所描述的“肖女士让她的同事帮她做地震的预测工作”一致,所以选A。
    本题给出的信息是错误的。题干的意思是:“肖女士和她的研究组测量了断层两侧的震动强度,确定了公元365年地震的震级。”原文中与之相关的信息出现在第四段第一句中:"Ms.Shaw and her colleagues calculate the likely intervals by measuring the motion of either side of the fault to find how often such large earthquakes would have to occur to account for that level of motion.”肖女士和她的同事测量了断层两侧的震动强度,并确定大规模地震多久发生一次才会引起这样的震动强度,从而推算出地震产生的大致间隔时间。由于所表述的行为目的不同,这句恰恰证明了题干上的说法是错误的。所以选B。
    文章没有谈到这方面的信息。题干的意思是:“由肖女士研发的地震预警装置现在在全球广泛使用。”文章中没有一句提到肖女士发明过地震预测装置,更没有谈及这种装置在全世界得到广泛应用这一点,所以选C。

    Eastern Quakes Can Trigger Big Shakes
    In the first week of November 2011,people in central Oklahoma experienced more than two dozen earthquakes.

    caused cracks in a few buildings and rattled the nerves of many people who had never felt a quake before.
    Oklahoma is not an area of the country famous for its quakes.If you watch the news on TV,you will see
    reports about all sorts of natural disasters一hurricanes,tornadoes,flooding and wildfires,to name a few.But
    the most dangerous type of natural disaster,and also the most unpredictable,is the earthquake.
    Researchers at the U.S.Geological Survey estimate that several million earthquakes rattle the globe each
    year. That mnay sound scary,but people don'I feel many of the tremors because they happen in remote and
    unpopulated regions.Many quakes happen under the ocean,and othlers have a very small magnitude,or
    shaking intensity..
    A magnitude 5.8 earthquake that struck central Virginia the afternoon of August 23,2011,was felt
    from central Georgia to southeastern Canada.In iilany urbanl areas,including Washington,D.C.,dnd New
    York City(Wall Street shown),people crowded the streets while engineer inspected buildings.Credit:
    Wikimnedia/Alex Tahak.
    Scientists know about small,remote quakes only because of very sensitive electronic devices called seis-
    mometers.These devices detect and measure the size of ground vibrations produced by earthquakes.
    Altogether,USGS researchers use seismornetero to identify and locate about 20,000 earthquaks
    each year.
    Although earthquakes can happen anywhere in the world,really big quakeg occur only in。erttiin areas.
    The largest ones register a magnitude S or higher and happen, on average,only once each year. Such big
    ones typically occur along the edges of Earth’s tectonic plates.
    Tectonic plates are huge pieces of Earth’s crust,sornetinies many kilometers thick.These plates cover
    our planet's
    surface ike a jigsaw puzzle.Often,jagged edges of these plates temporarily lock together. When
    riates jostle and serape past each other earthquakes occur. On。、crage,tectonic plates move very slowly一
    about the same speed as sour fingernails grow.
    But sometimes earthquakes rumble through portions of the landscape far from a plate'S edges.Although
    less cxpcctcd,these"mid-plate"tremors can do substontaI damage,Some of the biggest known examples
    rattled the eastern haif of the United States two centuries ago.Today,scientists are still puzzling over why the
    quakes occurred and when similar ones nught occur.

    The earthquake is the most unpredictable natural disaster.
    A:Right
    B:Wrong
    C:Not rnentioned

    答案:A
    解析:
    由文章第一段第三句话“Oklahoma is not an area of the country famous for its quakes.”可 知,俄克拉荷马州不是美国以地震多发而扬名的州,故应选B。
    由文章第一段最后一句话“But the most dangerous type of natural disasters, and also the most unpredictable, is the earthquake”可知,应选A。
    由文章第二段第二句中“people don' t feel many of the tremors because they happen in re- mote and unpopulated regions”可知,在发生的多次地震中,只有很少的会被人们感觉到,因为多 数的地震都发生在遥远的无人区,故选B。
    文章第四段中仅仅提到了地震仪能够监测到地震导致的地面震颤的面积和科学家们 用这种仪器所监测到的地震数目,故选C。
    由文章第五段最后两句的内容可知,8级或更高的大地震多发于地壳构造板块的边缘, 故选A。.
    由文章第六段第四句“When plates jostle and scrape past each other earthquakes occur." 以及常识可知,地壳板块只有在相互推挤和摩擦时地震才会发生,并不是任何一次的板块移 动都会导致地震,故选B。
    文章最后一段中提到,两个世纪前几次最强的板块中部地震袭击了美国东半部地区, 但文中只说这些是已知的地震中最强的几次,并未表明这几次地震中的某一次地震是历史上 最强的,故选B。第3部分:概括大意与完成句子

    A Great Quake Coming?

    Everyone who lives in San Francisco knows that earthquakes are common in the Bay Area一and they
    can be devastating. In 1906,for example,a major quake destroyed about 28,000 buildings and killed
    hundreds,perhaps thousands of people.Residents now wonder when the next"Big One"will strike.It's
    bound to happen someday. At least seven active fault(断层)lines run through the San Francisco area. Faults
    are places where pieces of Earth'S crust(地壳)slide past each other.When these pieces slip,the ground
    shakes.
    To prepare for that day,scientists are using new techniques to reanalyze the 1906 earthquake and pre-
    diet how bad the damage might be when the next one happens.
    One new finding about the 1906 earthquake is that the San Andreas fault split apart faster than scientists
    had assumed at the time. During small earthquakes,faults rupture(断裂)at about 2.7 kilometers per second.
    During bigger quakes,however.ruptures can happen at rates faster than 3.5 kilometers per second.
    At such high speeds,massive amounts of pressure build up,generating underground waves that can
    cause more damage than the quake itself. Lucky for San Francisco , these pressure pulses(脉冲)traveled
    away from the city during the 1906 event.As bad as the damage was,it could have been far worse.
    Looking ahead,scientists are trying to predict when the next major quake will occur. Records show that
    earthquakes were common before 1906.Since then,the area has been relatively quiet.Patterns in the data,
    however,suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62
    percent.
    New buildings in San Francisco are quite safe in case of future quakes.Still,more than S4 percent of the
    city’s buildings are old and weak.Analyses suggest that another massive earthquake would cause extensive
    damage.
    People who live there today tend to feel safe because San Francisco has remained pretty quiet for a
    while.According to the new research,however,it's not a matter of"if" the Rig One will hit.It',just a mat-
    ter of when.

    The highest speed of fault ruptures in the 1906 quake was more than 3.5kiiometors per second.
    A:Right
    B:Wrong
    C:Not mentioned

    答案:A
    解析:
    短文第一段的倒数第兰句提到至少有7条地质断层线穿越旧金山。
    短文虽然说旧金山大地震的破坏力非常大,但没有明确指出其程度是美国历史之最。
    从第兰段最后一句话可知答案。
    第五段的第二句话提到1906年前地震频繁。
    倒数第二段提到:城里超过84%的建筑是旧的、不坚固的。所以旧金山并没有为地震做好准备。
    第五段的最后一句话说科学家们顶测地震发生的概率荃少为62%,但是这并不意味着 科学家们就能预测出准确的时间,最后一段也只说明这是个时间问题,而没有说出具体时间。
    短文末尾提到:问题已不再是“是否”将会发生大地震,而是“什么时候”会发生。第3部分:概括大意与完成句子
